Abstract (en)
[origin: WO9802101A1] This invention is an atherectomy device for removing tissue from an artery. The device includes a flexible, elongated drive shaft (20) rotatable about a guide wire (15), the drive shaft having an enlarged diameter tissue removal section (28). The drive shaft and the enlarged diameter tissue removal section are comprised of helically wound wire. Wire turns of the proximal portion (30) of the tissue removal section have diameters that gradually increase distally at a generally constant rate thereby forming generally the shape of a cone. Wire turns of the distal portion (40) of the enlarged diameter tissue removal section have diameters that gradually decrease distally thereby forming a generally convex distal portion. At least part of the tissue removal section includes an external coating of an abrasive material (24) to define an abrasive segment of the drive shaft.
